Should help fill out at least the land section quite a bit. I've skipped some potential reprints that were shown with already known art as they may have been mislabelled as being in DMU. Same for the Raven Man. Surely we'll get confirmation about those later...
Number # 3 is Nephilim right? [...] it fits with the theme?
I don't know about that... Historically four-color creatures in a Commander set (with strict color identity rules) based on a plane focused on three-color combinations doesn't sound like a great fit to me. Unless they get rid of the four-colorness that's the Nephilim's USP (which I hope they'd be smart enough not to do, but then again, I wouldn't put anything past someone who's capable of thinking asymmetrical Slivers are a good idea).
Kyodai has one of those holostamps that currently, only rares and mythics have. Unless they decided to expand that, Unfinity-style, it's not an uncommon.
Interesting that a character as obscure as Azamuki, Treachery Incarnate gets a mention (albeit misspelled). I don't envy Creative's job of making this cyberpunk evolution of Kamigawa to not feel jarring, but little details like this give me a little more hope that they might actually pull it off.
TSP Mishra is not only a younger Mishra, he's an alternate timestream Mishra, so it's hardly fair to compare them. Besides, as said above, Mishra had Phyrexian augments in the Brothers' War novel and Urza's Saga (Endoskeleton), and there's no reason to believe Tezzeret was even alive during the Brothers' War, thousands of years before Alara block.
This isn't rocket science, if you don't want to play Slivers with global effects you should play Allies instead. And if for some BS reasons you don't want to make new symmetrical Slivers, you should cut the pretense of throwing enfranchised players a nostalgia bone and just make new Allies instead.
Frankly I'd prefer if R&D kept Slivers a relic of the past rather than destroy the mechanical identity of one creature type with potential by conflating it with that of others (Allies, "lords") and lessening all of them in the process.
Alas, R&D gonna R&D...
Worst nightmare of the MSE template makers? Worst nightmare of the MSE template makers, definitely. Mad props to those who would even try to get them to work, and even madder props to those who succeed.
Seems to be a fun mechanic, but with only three dungeons total you're gonna see all they have to offer pretty quickly.
Biggest downside of Asmorawhatever for me is that they went for the old-frame multicolored border instead of making a hybrid one. The MSE versions of them looked great, the one especially. Oh well.

[EDIT: Just saw a full, large-size version of the Phyrexian Altar art... And recognized Phyrexian Dreadnought's face... That's amazing.]

Likely, since (if the leaks are correct), Kyodai already has a card in this set.
